Technical Drawings - Helix-Tower 1

This collection shows technical drawings of the Helix-Tower 1, a continuously extendable and retractable tower construction. From 1989 onwards Zuse worked on the design of the height adjustable tower. In 1993 Zuse had accomplished the prototype HT1 on a 1:30 scale to test the construction. In 1992 he started sketching up a second model (HT2) on a 1:10 scale. The prototype can be extended to a height of 270 centimeters; the full-scale tower had been schemed to reach 120 meters. The analysis of archival documents and oral history reports revealed that Zuse intended his tower to be used for wind power installations, observation and radio transmission
